Multisig transaction signing error with Ledger Nano S on Mac

Description

When we attempt to sign a PSBT for a 2-of-3 native segwit multisignature output, it fails.

Error messages:

2024-01-23 23:52:36,523 ERROR [JavaFX Application Thread] c.s.s.c.DevicePane [null:-1] Signing Error: ('0x6a82', 'Error in <BitcoinInsType.REGISTER_WALLET: 2> command', '') com.sparrowwallet.sparrow.io.SignTransactionException: ('0x6a82', 'Error in <BitcoinInsType.REGISTER_WALLET: 2> command', '') at [email protected]/com.sparrowwallet.sparrow.io.Hwi.signPSBT(Unknown Source) at [email protected]/com.sparrowwallet.sparrow.io.Hwi$SignPSBTService$1.call(Unknown Source) at [email protected]/com.sparrowwallet.sparrow.io.Hwi$SignPSBTService$1.call(Unknown Source) at javafx.graphics@18/javafx.concurrent.Task$TaskCallable.call(Unknown Source) at java.base/java.util.concurrent.FutureTask.run(Unknown Source) at javafx.graphics@18/javafx.concurrent.Service.lambda$executeTask$6(Unknown Source) at java.base/java.security.AccessController.doPrivileged(Unknown Source) at javafx.graphics@18/javafx.concurrent.Service.lambda$executeTask$7(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.base/java.lang.Thread.run(Unknown Source)

Sign message steps:

1. Open Sparrow, and create transfer tx.
2. Sign PSBT, connect, scan and unlock Ledger, use Ledger to sign.
3. Get error message.

Both creating a new PSBT and signing an exist PSBT, we got the error message.

Discussed in the Telegram group - the Nano S is likely out of memory to store the wallet configuration.

I have already deleted all other wallets. There are 80kb free memory.
But when I signed multisig tx by Ledger Nano S in Sparrow, I got the same error messages.

I think the problem is not out of memory to store.

By the way, it works well when I use Ledger Nano S as a single signature wallet to sign tx.

Another thing it could be is a non-standard derivation path on the multisig wallet, which Ledger may not support. See bitcoin-core/HWI#702 as an example.

Solved it. Fingerprints of other 2 keystores were set to 00000000. I modified them, then it worked.

Really appreciate you.
